NIETAL WINDOW-FRAME.

SPECIFICATION forming part of Letters Patent N o. 755,585, dated March 22, 1904.

Application filed March 28, 1903.

To @ZZ whom, it may concern..-

Be it known that I, HENRY C. SMITH, a citi- Zen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Metal Window-Frames, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speciiication, in explaining its nature.

My invention relates to an improvement in metal window-frames.

It consists in the means whereby the separate parts of a framev made of rolled metal may loe fitted or joined together without any expensive joining or preliminary iitting of the rolled parts.

The desirability of the rolled-metal frame resides in the fact that by rolling the metal it can be formed in just such configuration and moldings as particularly fit it for making a window-frame. The metal has also when rolled just such a smooth and finished surface as is most desirable. One objectionable feature, though, to making the frame of rolled metal is that in order for the separate head, sill, and jarnb portions of the frame to properly join together or be united requires an expensive joining or fitting of the parts and which is attended with more or less waste of the rolled material. This is especially true of the ends of the jambs which unite with the head of the frame. In order to secure a proper sash closure and protection, the head of the frame is ordinarily formed deeply recessed or grooved, so that if the top ends of the jamb portions of the frame were to conjoin with or it against the head, as they ordinarily do, there would need be a special cutting or finishing of these jamb ends to properly conform to the grooves or recesses formed in the head. The same is true of the lower ends of the jambs, which unite with the sill, but in a lesser degree by reason of the fact that the sill is notordinarily made so deeply indented or grooved as the head. By my invention, however, I am enabled to eliminate any pecuniary objection to the use of the Serial No. 149,132. (No model.)

rolled-metal frame structure like as I have referred to, and this by uniting together the separate portions of the frame structure in a way that requires no special finishing of the rolled parts. How this is done, together with other various features pertaining to the adjustability and adaptability of the rolled-metal frame, can best be seen and understood by reference to the drawings, where- Figure 1 shows the rolled-metal frame structure in Vertical section. Figs. 2, 8, and 4- show details in construction thereof, to which mention will hereinafter be made. Fig. 5 shows the rolled-metal jamb as applied to the retention of sliding sashes. Figshows the rolledmetal jarnb having a face-plate of sheet or rolled metal, to which reference will hereinafter be made. Fig. 7 shows the rolled-metal jamb as applied to the retention of a pivoted sash. Fig. 8 shows a modified form of the rolled-metal jarnb as applied to the retentionv of sliding sashes.

Referring to the drawings, A represents the head of the frame, B the sill, and C represents the side portions of the frame or jambs. The head, sill, and jambs are made of separate pieces of rolled metal bolted together. The head and sill have a formation by which they will be best suited to the kind of sash or sashes which they inclose and are also formed with moldings suitable for their architectural litness and surroundings. The jambs C extend, of course, along either side of the window and between the head and sill and, like the head and sill, are formed in such a manner as will best be suited to the sash or sashes which they serve to inclose; but to this reference willhereinafter be made.

The jambs C are secured to the head and sill, y

ends of the jambs to the angle-pieces are designated c, and Z represents the bolts which secure the angle-pieces to the head or sill of the frame. There may be as many of these bolts used as may be necessary to obtain a proper retention of the parts. The bolts c, which fasten the jambs to the angle-pieces, may be made with full heads, or these heads may be countersunk, especially if they come in the runways of the jambs in order that there may be no break in their continuity. It is to be noted in connection with these angle-pieces that the jambs C have a longitudinal adjustment relatively to the head and sill. This adjustment is obtained by reason of the slots CZ', formed in the angle-pieces, and through which slots the bolts d extend, by which the anglepieces are joined to the head and sill. The slots, of course, permit of. some considerable degree of longitudinal play by the anglepieces, and consequently a longitudinal adjustment of the jambs is obtained, which are secured to the angle-pieces as before described. The feasibility of the adjustable jamb needs no comment.

By reason of the deeply grooved or recessed formation at the head of the frame and the inclined ledged formation of the sill the ends of the jambs if they were extended to fit or abut against the head and sill would have to be correspondingly formed or cut in order to secure a finished jointure. This joining, however,would be expensive. It would necessitate more or less waste of the rolled material and might prevent altogether the use of the rolledmetal frame. I have obviated this pecuniary diiiculty to the use of the rolled-metal frame by squaring the ends of the jambs a short distance from the head and sill, respectively, and then filling the intermediate section left between the ends of the jambs and head and sill with auxiliary portions or pieces havinga configuration substantially like that of the head or sill, and so adapted to make jointure therewith in continuation or extension of the jambs proper. I preferably make theseauxiliary pieces or portions as an integral part of the angle-pieces D, which unite the separate parts of the frame, as before described. As illustrative of the way in which this is done, I have shown in Figs. 2 and 4 the angle-piece D, having an extension D', formed especially to fit into a frame-head like as shown in Fig. l, between which head and the square end of the jamb the said extension is adapted to be interposed as an auxiliary continuation or extension of the jamb, and it is especially to be noted that this portion D is extended to lie contiguous with the top edge of the jamb, and especially to be Hush with its interior facing, whereby the jamb -is made to extend, as it were, and conjoin with the head of the frame with a finished jointure. 'This special formation of the angle-piece just referred to is especially to be distinguished in its formation from the angle-piece shown in Fig. 3, where it performs only the function of holding the two parts of the frame in union, and the jamb extends up to make its own jointure with the head of the frame. The angle-piece D, which secures the jamb'to'the sill, may also have an extension D, adapted to fill the space between the bottom square edge of the jamb and the sill,

j which extension, of course,would be formed so to become united. The rolled portions may p even be rolled in lengths and then frame-sections cut therefrom ready to be joined and without waste of material.- As before said, the formation of the 4rolled-metal jambs is such as will best suit them for the peculiar kind of sash or sashes which they inclose. As illustrative of their peculiar adaptability I have shown in Fig. 5 the jamb rolled so as to be adapted for the retention and guidance of vertically-movable sashes. Such retention and guidance may be obtained by means of the rolled exterior and interior flanges c' c2 and the sash-dividing flange c3.

In Fig. 8 the jamb is shown rolled, so as to provide grooved recesses c, which may receive plates extending from the sashes and which plates are adapted to slide in these recesses for procuring the sliding adjustment of the sashes.

In Fig. 6 I have shown a supplementary plate C used with the rolled jamb. This' plate may be formed of thin rolled or sheet metal, and it mayconnect with the jamb by any suitable rolled anged connection, as by being secured to the flanges c' c2 and braced by the dividing central flange c3. Inasmuch as the metal by its rolling is made to have a smooth surface this supplementary face-plate is unnecessary in so far as the covering up of imperfections or irregularities or roughness in the jamb is concerned; but it is a desirable adjunct to be used with the vertically-movable sashes, especially if weights' be used in order to cover up the openings c5, (see Fig. 1,) which are cut through each -jamb in order that the IOS IIO

IIS

weights may be inserted through the jambs l however, that the anges c c7, to which the considered the way in which I obtain the iinished jointure of the separate rolled portions constituting the frame.
